Abstract: This study aimed to assess the pollution of heavy metals, specifically Cd, Fe, Pb, Ni, Cr, Mn, and Zn, in the water filtration plants of DHA phase II Islamabad, Pakistan. As the zone relies heavily on these sources for in house and drinking purposes, eleven samples were collected and preserved for analysis. Laboratory testing, conducted for all samples using Flame Atomic Absorption Spectroscopy instrument, revealed that levels of Iron, Manganese, and Zinc were within accepted limits in nearly every sample. However, concentrations of Cd, Pb, Ni, and Cr exceeded PAK-EPA standards, suggesting potential health risks. The calculation of the Heavy Metal Pollution Index indicated that most samples were unsuitable for direct consumption, emphasizing the hazardous nature of the water for drinking purposes.
